What it does

• Metadata Extraction. Functions to extract and load relevant metadata from SPARQL endpoints. These loaders are compatible with LangChain but are flexible enough to be used independently, providing metadata as JSON for custom vector store int
• SPARQL Query Validation. A function to automatically parse and validate federated SPARQL queries against the VoID description of the target endpoints.
• MCP server with tools to help LLM write SPARQL queries for a set of endpoints
• Deployable Chat System. A reusable and containerized system for deploying an LLM-based chat service with a web UI, API, and vector database. This system helps users write SPARQL queries by leveraging endpoint metadata (WIP).
• Live Example. Configuration for expasy.org/chat, an LLM-powered chat system supporting SPARQL query generation for endpoints maintained by the SIB.
